When tech E&O is needed

Tech E&O is required by:

  • Enterprise customer contracts — multinational and government customers routinely require Tech E&O of S$5m to S$25m as a condition of engagement.
  • MAS-regulated financial services customers — technology vendors to financial institutions face MAS Notice 644 / TRM Guidelines flow-through.
  • Cloud service hyperscalers as customers — AWS, Azure, GCP partner contracts often specify E&O minimums.
  • SaaS marketplace listings — Salesforce AppExchange, Microsoft AppSource require E&O.
  • Tender requirements — SG government IT tenders specify minimum E&O cover.

What E&O covers

A Singapore Tech E&O policy responds to civil claims alleging:

  • Software defects — bugs in delivered code causing customer financial loss.
  • System integration failures — failed connection between customer systems and delivered technology.
  • Performance failures — system fails to meet stated SLAs.
  • Data corruption during migration, integration or processing.
  • Negligent advice or service in technology consultancy — standard PI cover within Tech E&O.
  • IP infringement claims — allegations that delivered code infringes third-party IP rights.
  • Defamation via media or content delivered as part of the service.

Pays damages plus defence costs.

Tech E&O vs general PI

For pure technology businesses, Tech E&O is structurally different from a general PI policy:

  • General PI is written for the "professional advice" trigger — legal advice, engineering calculations, accounting opinions. May not cover software defects in delivered code.
  • Tech E&O specifically covers technology delivery failure modes.
  • Tech E&O extensions: failure-to-deliver, breach of contract for technology services, infringement of third-party IP via delivered code.
  • Many Tech E&O policies bundle cyber liability for combined limits.

Combined Tech E&O + Cyber

Modern Singapore technology businesses typically buy combined Tech E&O + Cyber policies because the boundary between the two is increasingly blurred:

  • A data breach caused by a delivered software defect is both E&O (customer financial loss) and Cyber (incident response).
  • A failed integration causing customer data exposure spans both.
  • SaaS providers face combined exposures across the entire customer journey.

Combined policies typically have shared limit (e.g., S$10m total across E&O and Cyber) with per-claim sub-limits. Cleaner for the insured than two separate policies with seam risk.

Retroactive date discipline

Like all claims-made covers, Tech E&O requires retroactive-date discipline:

  • At renewal, the new policy must carry the SAME retroactive date as the original. Forward drift creates an uninsured tail for past project deliverables.
  • When switching insurer, retain the earliest retroactive date in force.
  • When closing the business or selling, buy run-off cover of typically 6 years (matches Singapore limitation period) to handle late-reported claims.
  • For SaaS exits and M&A transactions, the acquirer typically requires the seller to maintain run-off cover for 6 years post-completion.

Frequently asked questions

What's the difference between E&O and Professional Indemnity?

E&O is a specialised form of professional indemnity tailored to technology businesses. General PI covers professional advice failures (legal advice, engineering calculations, accounting). E&O extends to specifically technology-relevant exposures: software defects in delivered code, system integration failures, data corruption during migration, performance failures (system doesn't meet stated SLAs), cybersecurity failures. Many tech businesses now buy combined "Tech E&O + Cyber" packages with shared limits.

Who needs tech E&O?

Any business that provides technology services or software to customers and where customer financial loss could result from technology failure: SaaS providers, IT consultancies, cloud service providers, system integrators, digital agencies, web/app development firms, data analytics consultancies. Increasingly required by enterprise customer contracts as a condition of engagement.

Is E&O claims-made?

Yes. Like all professional indemnity, E&O is written claims-made. The retroactive date is critical — at renewal, the new policy must carry the same retroactive date as the original. When closing the business or selling, buy run-off cover (extended reporting period) of typically 6 years to handle late-reported claims.

How is E&O different from cyber liability?

E&O covers third-party claims for financial loss from technology failures (software defects, integration failures, performance failures). Cyber liability covers first-party costs of a cyber incident (incident response, business interruption, ransomware) and third-party privacy claims (data subject claims, regulatory defence). Modern technology businesses typically need both — Tech E&O + Cyber combined policies are common.

What sum insured is typical?

For small dev shops and freelance consultancies: S$500k to S$2m. For mid-market SaaS and digital agencies: S$2m to S$10m. For larger SaaS, cloud providers and system integrators serving enterprise clients: S$10m to S$25m+. Enterprise customer contracts often specify minimum E&O limits.
